Lenovo's top-of-the-line X1 Carbon laptop is no longer the sole X1 offering from the Chinese hardware manufacturer, with the company on Monday announcing the expansion of the X1 line.

Entering product range is a modular tablet, the ThinkPad X1 Tablet, which comes with three clip-on modules: A five-hour battery module that extends the length of time that the tablet can be used, from 10 hours to 15 hours; a projector module that includes a pico projector and an HDMI port; and an imaging module that makes use of an Intel RealSense camera.

The tablet can use a magnetic full-size ThinkPad keyboard that also includes the TrackPoint pointing stick in the middle of the keyboard and the standard ThinkPad three-button trackpad. Inside, the X1 tablet packs an Intel Core M7 vPro processor, up to 16GB of LPDDR3 memory, one USB3 port, a USB Type-C port, and up to 1TB of SSD storage that is expandable with the use of a microSD slot. A nano SIM port allows the tablet to make use of its LTE-Advanced functionality for connectivity.

Its display is a 12-inch 2160x1440 IPS panel, with the tablet weighing 795 grams on its own, and the keyboard being the heavier component, bringing 1.1 kilograms to the equation.

Covering the convertible laptop use case, the ThinkPad X1 range has been expanded to the ThinkPad X1 Yoga, a 17mm convertible that can optionally use a Samsung OLED display. The X1 Yoga makes use of, potentially, an Intel Core i7 processor, 16GB of DDR3 memory, 1TB of NVMe SSD storage, and LTE-A connectivity.

In the traditional laptop category, the 2016 X1 Carbon now can use 1TB of Samsung M.2 NVMe SSD storage, which the Korean giant launched in September, and LTE-A.

The X1 Tablet, Yoga, and Carbon are all able to use an optional WiGig wireless docking accessory that includes networking, video outputs, and USB ports. For the Carbon and Yoga, Lenovo claims its 65W power brick is now 58 percent smaller and 50 percent lighter than a standard power adapter.

On the desktop, Lenovo has announced the ThinkCentre X1 AIO that packs a 23.8-inch 1920x1080 IPS anti-glare display, a sixth-generation Intel Core i-series processor, up to 16GB of DDR4 memory, and up to 1TB of storage into an 11-millimetre chassis. Lenovo also announced the 27-inch 3840x2160 ThinkVision X1 monitor, which the company said is the first monitor to receive TUV Eye-Comfort certification.

The earliest member of the new line-up to arrive will be the IPS-display X1 Yoga this month, beginning at $1,449, with the OLED models to be available in April, with pricing yet to be announced for those.

The ThinkPad X1 Tablet will arrive in February from $899, and its battery module will be an extra $149, with the other two modules available in May. The projector module is set to cost $279, and the imaging module $149.

Also available next month will be the 2016 X1 Carbon from $1,299, with the X1 desktop all-in-one and monitor to follow in March. The pricing on the ThinkCentre X1 AIO will start at $1,029, and the ThinkVision X1 will cost upwards of $799.
